To all whom t may concern:

Be it known that I, ERICH C. HEMPEL', va

Tawa's, in the county of Iosco and State of Michigan, have inventedcertain new and useful Improvements invDishwashing Machines, of whichthe following is a specification.

In carrying out the resent invention it is my purpose to provide a dishwashing machine whereb plates, cups and saucers may be washedsimultaneously, and wherein subsequent to the Washing of the dishes thewater may be drained off and the dishes subjected to the action ofdraughts of air, so that the same may be dried. v

It is also my pur ose to provide a dish washing machine which willembrace the desired features of simplicity, efiiciency and durabilitwhich may be manufactured and markete at small cost, which may bemaintained and operated at a minimum expense and which will embodycomparatively few parts, and these so arranged and corelated as toreduce the possibility of derangement to a minimum. With the aboverecited objects in view, and others of a similar nature, the inventionresides in the construction, combination and arrangement of `parts setforth in and fallinv within the scope of the appended claim. n theaccompanying drawings: Fi re 1 is a longitudinal sectional view througha dish washmgmachine constructed in accordance with my invention.

Figure 2 is a cross sectional View 'on the line 2 2 of Figure 1. f'

Figure 3 is a fragmentary'sectional view through one of the cup holders.

Figures 4 and 5 are plan views of thev cu holders.

d igure 6 is a perspective view of a saucer holder.

Referring now to the drawings in detail, 1J designates a substantiallyrectangular casing equipped adjacent to its lower wall with a falsebottom 2 and provided in its top wall with a filling opening 3 closed bymeans of a cover 4. Mounted in the casing 1 above the false bottom 2'and spaced apart from such false bottom is a drum 5 that 1s circular incross section. The end walls ofthe drum 5 are equipped with trunnions 6that are journaled in the adjacent end walls of the casing 1 lso thatthe drum 5 may be freely rotated within the casing. This 5. has its sidewall composed of foraminous material 7 and the foraminous material isprovided with enlarged ingress openings that -are closed by `covers 8that are also formed of foraminous material, these. covers 8 beingremovable Vso that access ma be had to the interior of the drum, in orer to place the dishes therein in a manner to be presently described.-The false bottom 2 is shaped lafter the fashion of a trough, as clearlyshown in Figures 1 and 2 of the drawings, and the bottom wall thereof isinclined from one end toward the other and at its lower end communicateswith an outlet cock 9, which may be opened in order to drain the water.out of the trough after the dishes have been washed.

One of the trunnions 6 of the drum 5 is equipped with a beveled pinion10 that meshes with a single pinion 11 on the upper end of a verticalshaft 12 that is journaled in suitable bearings 13 carried by the rearwall of the casing on the outer side of such wall. On the lower end ofthe shaft 12 is a beveled pinion 14 meshing with a similar d pinion 15fixed upon the armature shaft of an electric motor 16 that is fastenedwithin the casing 1 to the bottom wall thereof below the false bottom2.' This motor 16 is under the control of an electric switch 17. Thus,when the motor 16 is energized, motion is transmitted through thebeveled gears andthe shaft 12 to the drum 5, so as to ref tate the drum5 within the casing 1.

At one end thedrum '5 is provided with uprights 18, and spaced apart todefine a rectangle and fixed to these uprights 18 at the bottom of thedrum 5 is a wire plate rack 19, while slidably mounted upon the rodsabove the rack 19 yis a rack 20 that cooperates with the rack 19, inorder to hold the plates securely within the rack after such plates havebeen placed within the racks through the ingress opening in the drum. Atits other end the bottom wall of the drum 5 on its innerI side isprovided with a cup rack 21 which is shownin detail in Figures 3, 4 and5 of the drawings, and comprises, in the present instance, a bottom bar22 fastened to the bottom wall of the drum. This bar 22 carries annuli23 suitably fastened to the bar and spaced apart'along the same. Theseannuli are of such diameter as to nicely receive the o en ends of thecups. Above the bar 22 is a ar 24 parallel with the bar 22 and havingits ends slidably mounted upon posts carried bythe bar 22 adjacent tothe ends thereof. This bar 24 may be locked in any position upon thepost 25 by means of set screws 26. This bar 24 carries relatively smallannuli 27 corresponding in position and number tothe annuli 23, andthese annuli 27 are of"such diameter as to nicely receive the bottomends of the cups, as clearly shown in Figures 1 and 3 of the drawings.Thus, after the cups have been .placed in the lower annuli the upperannuli carried.l by the bar 24 may be moved downwardly into engagementwith the small ends of the cups, so asl to clamp the cups securely inposition, the set screws 26 being manipiqulated for this purpose.

At the last mentioned end of the drum I also employ saiicer holderswhich, in the present instance, comprise vertical rods 28 secured inthedrum 5 and spaced apart to define a rectangle; These rods 28 carry bars29fwhich are ltwo in number, and spaced apart in .parallelism and the'bars 29. are

slidable vertically on the rods .28. Below the bars 29 the rods 28 carrya saucer rack -30 which cooperate with the rods 29 to h'old thedsaucers'in position, as clearly shown in Figure 1 of the drawings. The bars 29also carry spacer plates 31'adapted to be `interposed between thesaucers, as vclearly shown in Figures'l and 6 of the drawings,

so that the saucers will be held spaced apart when placed within therack;

When the drum 5 is at a state of rest and as shown in Figure 1 of thedrawings, the motor 32 -is energized by. passing-electric wires throughthe openings 35 and connecting thersame with the socket which iseleetrically connected with the motor 32. During the time that the motor32 is energized, g the drum 5 yremains stationary i,

Mounted' within the drum V5 centrally thereof is an electric motor 32and fast to the end's of the armature shaft of the motor 32 are fanblades 33 adapted to be rotated when the motor is energized toV drivethe air through the drum and over the dishes `therem.

The rear wallof the casing 1l is equipped with a housing 34 that encasesthe ldriving connections` between the motor 16 and the drum and at itsupper end this housing 34 is formed with a hand opening 35, by means ofwhich the plug 37 may be insertedin and lremoved' from socket 36 carriedby the adjacent end wall of the drum 5. Wiring 38l leads from the socketand is connected to the motor in anysuitable way.

In practice, the dishes are placed within the drum, as previouslydescribed, and the cover 4 removed so that the housing may be filledwith Water and soap or other cleansing solution for the dishes.l Thecover 4 isunow replaced and the motor 16 energized, thereby revolving.the drum 5 to thoroughly cleanse the dishes in the drum. Aftei` thedrum has rotated for a suflicient period of time to cleanse the dishes,,the motor 16 is shut olf and the drain cock 9 opened, so that the watermay drain out of the housing. The motor 32 is -now energized so that thefan blades 33 will blow air .over the dishes in order to drythe same andafter the dishes 'have been dried the cover sections 8 of the drum maybe removed 'so that the dishes may be taken out of the drum through theopening 3.

While I have herein shown and described one preferred form of myinvention by way f of illustration I wish it to be understood that I dono t iimit or confine myself to the precise detailsjof constructionherein described and delineated, as modifications and variations may bemade within the scope of the claim and without departing from. thespirit of my invention. I -Iaving thus described is claimed as lnew, is
